The upper ends of the latches .39 are connected by the rods 44, said rods being connected to thelevers 45, there being a series of latches upon each side of the 'ihe pins 46 are removably inserted by removing the pins desired number of the latches may be thrown out of operation as required to open one door without opening the remaining doors. A perforated rack 47 is mounted upon the end of the carbody beside each lever 45, and pins may be inserted through the openings 48 in said rack to hold the levers 45 in any de ired position. The rods 44 extend throughhorizontal openings 49 in the posts 50, said posts being framed to the side sills and the side boards 51 being attached to said posts. if desired, the levers 45 may be spring-actuated, so that when the doors are closed the latches will automatically engage the dogs 43.

l Wish to call especial attention to the construction ol my body-bolster, which comprises the lower part 52, supporting the center Vand intermediate sills 12 and 13, the pedestals 53 and 54, extending upwardly from the lower part 52 between the sills 12 and 13, and the arms and 55, extending laterally from the upper ends oi the pedestals 53 and 54 and niortised through the sills 36 and 37 to support said sills, the arms 55 and 56 being triangular in crosssection, yas shown in Fig. 2. rilhe brace 57 connects the upper ends of the pedestals 53 and 54, as shown in Fig. 3.

Ey the use of my improved body-bolster 1 am enabled te use the long dump-doors extending' from the cross-sills 19 and 20 to the ends of the car, said dump-doors covering' the cartrucl, passing under and swinging up against the arms ol? the body-bolster, thus protecting the truck from. the contents of the car.

the ends of the lower part ot' the body-bolster, said. shoulders forming stops to limit the fall of the doors.

Supposing that the dump-doors are open,

'the winding-tad is operated in the ordinary .it the doors are' too heavy to be all operated at once, either of thehooks 34 or 35 may be put ontoi' use and the doors upon one side closed independently of the other side. When When these long doors swing dowri; wardly, they rest upon the shoulders 58 upon it is desired to dump one door only, the pins 46 of' the doors not to be dumped are'removed. rihen the lever 45 is operated to dump the other door. i also wish to call especial attention to the construction whereby the latches 39 are concealed in the side sills 36and 37,-thereby being protected from in- ]ury.

The upper surfaces of the truss cross-sills and the upper surfaces of the body-holsters are A-shaped, so that they willbatch none of the contents of the car. ,C

By means of the cams'rand` ,leverage i am enabled to close the doors perfectly tight, so that the contents of the car will not leak out as in ordinary dump-cars. A

' in a companion application entitled Bodybolster-s, filed the 19th day of February, 1904,

Serial No. 194,374, I have shown and claimed the body-bolster by itself, and I do not wish to make such claims in this application.

6. Adump-car, comprising the combination with a car having a hopper-shaped bottom, a plurality of dump-doors leading from the bottom, cams attached to said doors, shafts rotatably mounted, arms extending from the. shafts and engaging the cams to close the doors, operating-arms attached to the shafts, rods con? necting the operating-arms together, a wind- IOO ing-steif -connected to said rod, so that by winding the staff the doors are closed, and means of holding the doors closed, solistentially as specified.

7. Adumpjcar, comprising the combination -with a car having a hopper-shaped bottom, :i

rdoors, operating-arms iit-tached to the shafts,

a rod connecting said operatiiig-arms, means of operating' said rod, and moans of holding the doors closed, substantially :is speciiied.

8. A dump-car, comprising' the combination with :i cur having` :i hopper-'slmpod bottom, it plurality of dump-doors londingfroin the hottom, earns attached to'sziid doors, shafts :'otiitably mounted,:irn1s extending- 'frolnthc shafts and engaging the coins to close the doors, means of operating' said shnt'ts, snaps for holding the doors closed, sziid snaps lining emhedded in the side sills of the car and protected from injury, and means 'of operating the snaps, shstantially as specified. v

9.l A dumpfcar, comprising' the combination with a, car having :i hopper-shaped bottom, e
